Someone held up a ‘Wenger Out’ banner behind Jeremy Corbyn as he was speaking.

A pair of cheeky pranksters smuggled the hand-scrawled sign into the background of his speech in Royal Leamington Spa, this afternoon.

The banner has become something of an internet sensation in recent months, with some Arsenal fans growing frustrated with embattled manager Arsene Wenger - and internet jokers 'photobombing' broadcast cameras with banners at any given opportunity.

Meanwhile, Corbyn has faced comparisons with the football boss, being called the “Arsene Wenger of Politics” by GQ Magazine.

And last month, in a frosty exchange on the Good Morning Britain sofa, Piers Morgan reeled off a string of similarities between the two leaders.

He said: “Blind dogma. A culture of laziness. Neither are bothered about actually winning. Both are un-sackable. They refuse to listen to their own people. They didn’t ‘see’ it. They have a recent blueprint of success that they’re not using - and both are dragging a once-great institution down with them.”

Corbyn brushed off the comparison as “nonsense” and denied being lazy, insisting: “Both of us are very hard working people.”

Life-long Arsenal fan Corbyn has described himself as a "Wenger man".

In another chat with Morgan in March, he said: "I'm an Arsenal supporter, as you know Piers, as indeed you are, you have a different position on Arsene Wenger than I do.

"Arsene Wenger is a very intelligent, very sharp, very thoughtful manager. He has kept Arsenal in the Champions League in every season since he became the manager of Arsenal despite the stadium move and everything else.

"We had a 2-0 win on Saturday - let's get behind the team. I'm behind Labour - you and I together can be behind Arsenal."
